Source: https://www.zonguru.com/pricing ## Key features - **AI Readiness Score:** Scores every listing from 0 to 100 and ranks them by fixable gap and revenue at stake, so the most valuable fixes come first. - **Listing rewrites:** Rewrites titles, bullets, descriptions and shopper questions in one pass for Amazon's A9 search and its AI shopping assistant, within Amazon's 75-character title cap. - **One-click publishing:** Shows the before and after for approval, then publishes the new copy to Amazon and confirms it is live. - **Nightly monitoring:** Checks watched listings nightly for score drops and outside edits, and more often for suspensions and a lost Buy Box. - **MCP access:** Every subscription can connect Claude or another MCP-capable AI tool to Helix to pull Amazon data and run rewrites from there. ## Good for - Brand owners who want listings rewritten for Amazon's AI shopping assistant - Agencies managing listings for several Amazon clients - Sellers on Amazon US or UK with a catalog of up to 100 key listings ## Worth knowing - Helix works only on the US and UK Amazon marketplaces. - Plans need a Seller Central connection on an Amazon Professional selling plan. - Extra rewrites are bought as credits at $49 for one or $99 for three; credits bought this way never expire. - ZonGuru's older product and keyword research tools are no longer on its pricing page, which now sells only Helix. ## ToolGPA grades **GPA: 1.4 out of 4**, graded Oct 18, 2026. ZonGuru now sells one thing: Helix, which scores your Amazon listings for search and for Amazon's AI shopping assistant, rewrites them, publishes the new copy and watches it nightly. It's US and UK only. At $124 a month for 5 rewrites, it costs more than suites that write listings alongside everything else. - **Value for money: D.** Graded against the suites it's listed beside. Helix Starter is $124 a month billed annually at $1,490 ($149 monthly) for 15 watched listings and 5 rewrites. Helium 10's Platinum is $99 with an AI listing builder and all its research, and extra Helix rewrites are $49 each. - **Free plan and trial: D.** The free AI Readiness Score rates a live listing from 0 to 100, with no card. It doesn't rewrite or watch anything, though, and there's no trial of Helix itself, so the free part does none of the paid job. - **Features: D.** Helix does one narrow job, listing copy: scoring, rewriting, publishing and nightly checks. Only the US and UK marketplaces are covered, and ZonGuru's older product and keyword research is gone from its pricing page. - **Ease of use: C.** No rating on record. The score needs nothing, but Helix needs a Seller Central connection on a Professional selling plan, and you approve each rewrite before it goes live. - **Platforms and integrations: C.** Web only, on the US and UK Amazon marketplaces. It connects to Seller Central, and every plan includes MCP access for Claude or another AI tool. No phone or desktop app. These are ToolGPA's own grades.

That is not a weekend's work, with an AI app builder or without one. That makes this kind of software worth paying for, not this one in particular: 14 of the 16 other Amazon seller tools grade higher. It costs $1,488 a year. - You could not: Data from Amazon's seller tools and years of sales estimates. - You could not: AI features, unless you pay a model provider for each request yourself.
